Outlook has ever been EVIL and a PITA (think about backup), M$ doesn't like other server solution (I mean, they don't like you use outlook without exchange), so such a decision is not surprising.
Thanks for the reply.
M$ is often the problem but given that 95% of users/businesses use Outlook I would have a difficult to impossible task to try to change them.
My posting here was simply to warn others that if they are going to investigate/use/install etc then they should be aware of what is a significant change to the usefulness of this software.
Perhaps someone could add to the top of the wiki for Zarafa I would but don't have permission.
What I need for my small business customers is a server back end that works with MS Outlook 2010 & 2013 (hopefully newer versions as well).
M$ Small Business Server not longer exists and therefore Exchange is now out of reach for most small business customers.
I had only very recently begun testing of Zarafa and all indications are good that it would work well for small business customers.
I am still hopefully that Zarafa may change their minds and continue to support the Outlook plugin, As can be seen on the Zarafa forum many IT & business are very upset by the anouncement. Maybe Zarafa will extend their plugin support or maybe they will out source or give the plugin to others to maintain if not then its time to find another product that works with MS Outlook. While waiting for Zarafa's final word (mid March 2015) time to do some research on other possible software.
I would ask of anyone reading this please share your experiences using exchange like replacement's - Easy to install, costs and how well they work with SME etc.
Software like -
Zentyal (sound good dose it work)
Kalab
Sogo (integrating with SME & Outlook)
Zimbra
Kerio
Icewarp.com
Any others that might be relevant.
Thank you
